2) determine the value of k for which the system of linear equations has no solution
2x-y=3
4x+ky=5 Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! (2,a) and (5,-3)
slope
=(-3-a)/2
is parallel to the line passing through the points
(4,8) and (-5,a+1)
slope
=
the lines are parallel so the slopes are equal
